> "Mainstream economics" is doing a lot of heavy lifting.
As is "mainstream medicine" or "mainstream climate science". If you don't trust mainstream science, you must be either extremely smart or just delusional.
economics isn't a hard science though; and there is a lot of politics underlying a lot of theory there (see the laffer curve/trickle down etc)
Soft sciences are not at all the same thing as hard science.
Surely you can see that not trusting mainstream economics shouldn't be as controversial as the hard sciences. Mainstream economics consistently fails to make correct or replicatable predictions.
